Intensive research has been carried out in the past few years on the occurrence and behavior of dechlorane plus (DP) in the environment, biota and humans. This review summarizes the information and research results generated since DP was first identified in the environment in 2006. We describe the reported measurement methods for DP and provide an integrated picture of its occurrence and behavior as an environmental contaminant. DP in ambient air and sediments is characterized by strong source related concentration elevations and temporal trends reflecting commercial use. Long-range atmospheric transportation of DP has been observed in remote regions, indicating a global presence of DP. Levels of DP in biota and in humans further reinforce its source related distribution. The change in DP isomer ratio in various environmental matrices from commercial products indicates that the behavior of the two isomers is not the same in the environment or in biota. With only limited data available so far, the biomagnification of DP in aquatic biota has not been conclusively demonstrated. This review also looks at reported dechlorination products of DP that might be of interest in future research.
在过去的几年中，人们对环境、生物群和人类中十氯酮（DP）的发生和行为进行了深入研究。本综述总结了自 2006 年 DP 首次在环境中被发现以来产生的信息和研究结果。我们描述了 DP 的报告测量方法，并提供了其作为环境污染物的发生和行为的综合情况。环境空气和沉积物中的 DP 具有强烈的与来源相关的浓度升高和时间趋势，反映了商业用途。DP 的长距离大气传输已在偏远地区观察到，表明 DP 具有全球性。生物群和人类中 DP 的水平进一步强化了其与来源相关的分布。从商业产品中各种环境基质中 DP 异构体比率的变化表明，两种异构体在环境或生物群中的行为并不相同。由于目前只有有限的数据可用，因此 DP 在水生生物群中的生物放大作用尚未得到明确证明。本综述还研究了 DP 的报告脱氯产物，这些产物在未来的研究中可能具有重要意义。
